Customer Training MaterialNotes on Workshop 2.1
The first workshop is extensively documented. As this course
progresses, students will become more familiar with basic
Workbench Mechanical functionality (menu locations etc.), thus
subsequent workshops will contain less details.
Throughout these workshops menu paths are documented as:
First pick > Second pick > etc..
Workshops begin with a goals section followed by an assumptionssection.

Customer Training MaterialGoals
Using the Stress Wizard, set up and solve
a structural model for stress, deflection
and safety factor.
Problem statement:
The model consists of a STEP file
representing a control box cover (see
figure). The cover is intended to be used in
an external pressure application (1.0 MPa).
The cover is to be made from aluminum
alloy.
Our goal is to verify that the part will
function in its intended environment.

Customer Training MaterialAssumptions
We will represent the constrains on
the counter bores, bottom contact
area and inner sides using frictionless
supports.
Frictionless supports place a normal
constraint on an entire surface.
Translational displacement is allowed
in all directions except into and out ofthe supported plane. Since we would
expect frictional forces to at contact
areas this is a conservative approach.

Customer Training Material. . . Results
Plotting a models deformation often provides a reality check in
structural analysis. Verifying the general nature (direction and
amount) of deflection can help avoid obvious mistakes in model
setup. Animations are often used as well.

After reviewing stress results expand the Stress Tool and plot safety
factor. Notice the failure theory selected predicts a minimum safety
factor of just over 1.

Notes on Figures:
Figures are not limited to results items. Adding a plot of the
environment branch, for example, will include an image of model
boundary conditions in the Report.
Figures are independent. You may set up individual figures and have
their orientation, zoom level, etc. retained regardless of the active
model orientation or other figures.
Individual branches can have multiple figures associated with them.
